ASSIGNOR, BY MESNE ASSIGNMENTS, TO

CHICAGO-CLEVELAND CAR ROOFING COMPANY, OF CHICAGO, ILLINOIS, A CORPORA- TION OF DELAWARE CAR-UNCOUPLING DEVICE Application filed May 31,

This invention relates to improvements in hand operated uncoupling devices for railway cars and the like, and more particularly to improvements in the parts that cooperate to lift the locking pin of the car coupler to uncouple the cars. I

Objects of the invention are to provide an uncoupling device, including brackets there for, that is readily and easily assembled without requiring bending of any parts and which when assembled will remain in operative position until intentionally removed, and which is readily and easily removed without bending or straining any of the cooperating parts; the provision of a bracket formed ofa single piece of metal into which the operating rod may be rotatably secured by merely setting the rod in slots in the brackets and inserting a key through said brackets-so that one side of the keyrests againsttherod andtheopposite side of the key may engage the bracket; the provision of a lifting rod having one end formed into a hub so that any movement of the coupler will not strain the connection between the lifting rod and the operating rod;

the provision of an uncoupling device that is easily manufactured and assembled and at less expense than has heretofore been possible; and such other objects and advantages of the invention as may be found to obtain in the structures hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification and showing for purposes of exemplification, a preferred form and manner in which the invention may be embodied and practicechbut wlthout limiting the claimed invention specifically to such 4) illustrative instanceor instances:

Fig. 10 is a perspective view of the key.

For purposes'of illustration, I'have shown on the drawings a wooden car end 11 to which brackets 12 are secured. These brackets, in the present instance, are made from a single piece of pressed steel and are formed to provide rear flanges 13 adapted to be secured to the car by fastenings 14. Extending out from the inner extremities of these flanges 13 is a member 15 that receives the operating rod. This member consists of sidewalls 16 joined together by a bottom wall 17,'and the walls 16 are flanged inwardly at 18 to provide a top wall. The top flanges 18 and side walls 16 are cut away at 19 to provide an opening 20 into which the operating rod 21 may rest, in order to rotatably bear on the rounded l0wer edges ofthe opening 20 in said side walls 16. After the rod 21 is placed in the opening 20, a key 22 is inserted into the chamber 23 defined by the flanges 18, side walls 16 and bottom wall 17. When the key is inserted into the chamber 23 the bottom 24 thereof rests on the operating rod 21 and the top 25 makes contact with the flanges 18. The key is perforated, as at 26, so that a cotter pin 27 may be inserted through the key to prevent it from falling out. The bracket is pressed out at 28 in order to strengthen thejunction of the side walls 16 and the flanges 13.

From the foregoing it will be apparent that the operating rod may be eflectively secured on the end of the car without requiring bending of the coacting elements in assembling,

and that the assembly of the uncoupling devices is greatly facilitated.

The operating rod 21 is provided at one end with a crank arm 29, which when lifted rotates the operating rod 21 that lifts the lifting rod to raise the locking pin of the carcoupler to unlock the coupler. The rod 21 is bent outwardly at 31 parallel with the coupler and this member 31 is bent upwardly at its end to provide a pintle'32.

The lifting rod 33 is bent back at one end to form a hook 34 that is passed through an eye 35 in the locking pin 36 of an uncoupling device 37. This hook insures operative connection between the lifting rod 33 and locking 1 pin- The lifting rod 33'is of reduceddiameter at 38 in order to allow some play between the rod and locking pin since the coupler is sub i'ect to lateral swinging movement at times.

At its other end the lifting rod is twisted or formed to provide an eye 39, that functions as a hub, integral with the rod 33,.and the material beyond and below the eye is bent/back at.

451 inthe direction of the main bodyof the-lifting rod and towards the coupler, and in the present instance this return bend formsa stop t2 located directly below the main body of the rod 33.

The lifting rod 33 maybe assembled on the operating rod by placing the rod 33 overand parallel with the portion 31, andplacing the eye 39 over the. pintle 32 and the hook 34: over the bend 43 in the rod 21, then swing the liftingrod 33 outwardly, away from the car end and towards the coupler. The bend 41 limits the outward movement of the lifting rod, and inward movement of lifting rod is limited by the coupler. The stop 42 limits the downward movement of the pintle 32, and therefore the device is capable of accommodatingitself to the various movements of the coupler without danger of the parts accidentally becoming disengaged or rendered in operative and without causing strains on. any of the coacting parts.

'When the crank 29 is lifted, the rod rotates in the brackets 12: and the member 31 raises, causing the pintle 32 to grip through the eye 39 and the material forming the bend. 41, thereby lifting the lifting rod 33 which raises the locking pin 36.

The invention as hereinabove set forth is embodied in aparticular form of construction but may be variously embodied within the scope of the claims hereinafter made.
